Trust no one. Wrap every single operation in parentheses
The thing with PEMDAS is that it's slightly inaccurate. (P)(E)(MD)(AS) would be a better (if much more convoluted) way to write it. Multiplication and Division are on the same "tier," so you do them at the time, or rather, from left to right. Same with Addition and Subtraction.
Ergo, in the above equation, after doing the parenthesis you are left with 6/2x3. You're supposed to do 6/2 first, leaving you with 3x3, or 9. Comparatively, if you do multiplication before division (as PEMDAS normally suggests) you'd multiply 2x3 first, get 6, then solve 6/6 for 1, which is incorrect.
Hope this helps!
EDIT: Goddamned Reddit formatting, italicizing my words.
"NOTE: Even though Multiplication comes before Division in PEMDAS, the two are done in the same step, from left to right. Addition and Subtraction are also done in the same step."
EDIT 3: Thanks for the gold, kind stranger!
EDIT 4: Apparently, it's actually written ambiguously and both answers are technically correct (though 9 is more accepted), according to various comments all over this post that I won't repeat for fear of being a broken record. Syntax errors and all that. But, assuming the equation is read as 6/2x(2+1) then everything I said is still perfectly accurate. Probably. I'm not a math professor, so my only real credentials is a high school diploma. ¯\_(ツ)_/¯
The fact that he's wrong makes it funnier.
Side note: Score one for smartphones!
I had my very own iamverysmart-moment right now. I mistook the division sign for a plus and thought to myself:
"Nobody got the actual right answer, why am I the only one that gets this simple math?"
Then I saw someone using a / to explain how it works and immediatly was ashamed for my iamverysmart-ery
Why is it always quantum? Why not something like particle or material physics?
Quantum has become a vulgar, derogatory word by being associated with iamverysmart type of guys in popular culture.
It's always quantum because you can sound smart without actually understanding it at all. Quantum (not to sound "I am very smart") isn't particularly hard, it's actually just fucking weird. Most people know a decent amount of physics without trying simply because physics is the study of the laws of the universe and you live in the universe, the same way you know all the important laws of the country without going to law school. But quantum only affects things on the level of particles, so why the fuck would the average person know anything about that.
I'm a physics major, and I took a semester of quantum. Shits weird. I don't really understand a lot of it, but if I wanted to I could spout useless facts to sound smart, because the average person can't call me on my bullshit.
I study quantum physics in Latin. It's more challenging that way.
I make it harder by not going to class
"Everyone has a mask. It only matters which one they put on."
Shouldn't it be 'everyone has masks.' If you only have one mask, it'd be the only one you'd put on.

"Fuck it Mask Off."
TFW you could explain something easily but you really need to force the words you learned a few minutes ago.
I actually recognize that textbook! The problem he's talking about is an example problem done for you in the book and arguably the easiest one...so he's essentially bragging that he read something explained step by step for him
Only if I'm lucky enough to be in Cartesian coordinates.
I like yellow.
One of us has to be colorblind because I don't see any purple here
Basically, since purple prides himself on solving such a simple math equation, yellow is being a smartass and acting like it was sooo difficult, to prove a point that maybe purple isn't as smart as he thinks he is. However, this point goes completely over Purple's head, who only continues to speak as if he is the smartest person in the world, much to our amusement and secondhand embarrassment.
Yellow took it all so well. Yellow seems like a good person
"advance the human race forward beyond this primitive instinct." Does he/she realize that by not fucking the human race will go extinct?

This guy posts so much shit like this he could have his own subreddit.
I always find it baffling that smart people don't think they're smart and stupid people don't think they're stupid.
He looks like an off brand Eminem
I guess they don't teach self awareness
Bitch, you got destroyed. Have a nice day.
Well he's wrong. The human eye can only see 2 frames per second. 1 frame per eye.
Did you just hide your username in your comment but let his comment to have +Gerben at the start ? :D

"You think I'm not smart? Well, I'll call you a "gay piece of shit"! Do you STILL think I'm not smart?!?!"
I love the "I'm only" age throw in like we're supposed to fall over with amazement
The adults around me in my youth convinced me that I was gifted and talented. It wasn't until I became an adult that I found out that I have an IQ of 94, so I am medically retarded. I had to cope with this fact alone in adulthood.
well he's got me there
At age 7, I began Googling
Destined for greatness
Oh you think intelligence is your ally? You merely adopted its precepts, I was born in it, molded by it. I didn't see idiocy until I was man, and by then it was nothing to me but pitiful.
He's quick. I didn't start googling myself until I was about 12.
I'm only 14 xD
